What is spacetime? Matter or energy or BS? Real thing or unicorn fart? How does gravity bend spacetime? What is the precise mechanism? What is the curvature of spacetime? Matter or energy or BS? How does space tell matter how to move? What mechanism? What language?

Gravity is the most accurate measured fundamental force between two lead balls in the labs. How do scientists measure spacetime curvature between two lead balls?

Relativity tards think gravity is not a force but the gravity of a black hole can attract or bend light to make it disappear. They think gravity is not a force but gravitational waves propagating in space at 3 x 10^8 m/s. A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.[1] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. Wiki How to deform spacetime? What mechanism? Monkey's story becomes mainstream science, so sad.
